Vince Hannemann began building the Cathedral in 1988, when he was in his mid-twenties. He's added to it steadily ever since, and he estimates that it now contains over 60 tons of junk. "People ask me all the time, 'What made you want to do this?' Like it had some sort of profound meaning. I just did it because I liked it. And when I stop liking it I'll take it down."
